I tried to make this lick sound really bluesy and greasy as possible against our Locrian track. The opening line is a G# Minor 7(b5) arpeggio line which I add a blues bend too.

The second half of this lick is derived from an E9 arpeggio. E7 is a diatonic chord substitution for the G# Minor 7(b5) and therefore we can substitute the arpeggios of each chord too. Try to make the phrasing of the notes really bluesy and slinky over the groove. You should be able to push and pull the beat a little bit too.

More on diatonic and modal chord substitutions for improvising in my next course stayed tuned!
